Factors influencing power consumption and power-saving measures in ESR process [PDF]

China Foundry, 2019
Since the USA patent of electroslag remelting (ESR) metallurgy was held by P. K. Hopkins in 1940, the ESR technology has now entered a relatively mature stage after a 70-year history of development.

Effect of the Al2O3 Content in the Slag on the Remelting Behavior of a Bearing Steel

steel research international, Volume 91, Issue 12, December 2020., 2020
The influence of the Al2O3 content in the remelting slag on chemical reactions and the formation of nonmetallic inclusions (NMIs) during electroslag remelting of a bearing steel is focused. In addition, numerical simulations on the NMI‐formation are presented, allowing for a better understanding how the type of NMI can be adjusted.

Profile Cross Rolling of High‐Interstitial Austenitic Stainless Steels for Application in Plastics Extrusion

steel research international, Volume 91, Issue 5, May 2020., 2020
Cold rolling is applied to machined preforms to strengthen the subsurface. Together, the outstanding work‐hardening potential of the corrosion‐resistant steel and the forming procedure facilitate a novel wear protection method for axisymmetric and helical parts.

Effect of Different Power Supply Modes on Inclusion in 304L Stainless Steel Electroslag Ingot

Metals, 2023
The use of low frequency or DC (i.e., direct current) operation in the electroslag remelting process may lead to the electrolysis of some oxides in the slag pool, which will adversely affect the cleanliness of the electroslag ingot.

A Method for Parameter Identification of Combined Integrating Systems

Mathematical Problems in Engineering, Volume 2020, Issue 1, 2020., 2020
This manuscript presents a novel structure of combined integration in the process industry and proposes an efficient method for identifying its parameters. Combined integrating processes are delay‐time processes that widely exist in the industry. Conventional identification methods have a low‐identification accuracy, a large vibration amplitude of the ...

Effective Electroslag Remelting of Superalloys

Superalloys 1972 (Second International Symposium), 1972
In order to take full advantage of electroslag remelting, it is necessary to optimize the most important properties, such as structure, chemical uniformity and inclusion control by careful choice of the remelt parameters, since these properties essentially determine the acceptability of the final part.

Influence of Viscous Dissipation on Wear Behavior and Hardness Evolution of Tool Steels in Glass‐Fiber‐Reinforced Polymer Processing

steel research international, EarlyView.
Tool steels tested under injection molding conditions with glass‐fiber‐reinforced polymers, revealing how viscous dissipation drives hardness loss, even in PM grades. A sharp rise in wear with increasing injection volume rate and thermomechanical load uncovers striking material differences.

Tailored Hardening and Isothermal Bainitizing of Additively Manufactured Nitrogen‐Enhanced Martensitic Chromium Steel

steel research international, EarlyView.
Tailored heat treatments transform additively manufactured high‐nitrogen martensitic Cr steel from austenitic as‐built condition to high‐hardness states. Isothermal bainitizing at 250°C generates an ultrafine nanostructure and achieves higher hardness than conventional hardening and tempering, highlighting a promising postprocessing route for laser ...

Transformation of the Completely Enclosed Atmosphere in Ordinary Electroslag Furnace and Its Influence on Typical Steel Grades [PDF]

Teshugang
As the quality of electroslag steel continues to be improved， the ordinary electroslag furnace requires urgent upgrading to a fully airtight atmosphere protection system， aiming to address issues such as element burning loss， oxygen and hydrogen increase，
